Letters Patent No. 99,61 3, dated February 8, 1870.

IIMPROvEMENTIIN APPARATUS FIOR DRYING- FISH .AND OTHER SUBS'TNCES. l

The Schedule referred t`o in 'these Letters Patent and making part af the same.

v To 'whom it may concern.-

Be it known that we,W1LLIAM J. HOOPER, THEO :conn Hoorna, and ORAZIO Loco, of the city ofBaltimore, and State of Maryland, have invented ,certain Improvements in I {ilns for Drying Fish, and other Substances, animal or vegetable, of which the fol-l lowing is the specification.

The nature of our invention consists in a dryingkiln, wherein fish or other substances, animal or vegetable, are placed in abasket or baskets, made either..`

of rods .of iron or ,perforated'iron pipes, arranged and connected with a main pipeor pipes, for the introduction of. heated air, or other gases. e

The cover or top ofthe kiln has aperforated fals top or perforated pipes, Vfor the introduction of heated' air or otherl gases, and vapors of hydrocarbons when such hydrocarbons are required during the operation Aof drying fish, or other substances, animal or vegetable, for the purpose hereafter more'fully specified.

Reference being had to the accompanying letters ofthe drawing- 1 Figure 1 is a front view of the kiln.

Figure 2 is a. longitudinal vertical section, showing two forms of baskets, either of which may be used.

A is an air-pipe, connecting with the false top of the cover of the kiln.

a, is another air-pipe connecting with vthe basket B.

a is an exhaust air-pipe, takingthe `fair either from A or a.

B is a basket, made of perforated hcw it is suspended in thekiln.

C is the bottom of the basket B, madeof rods or perforated pipes, attached to the basket B b'y hinges.

The kiln has a jacket, j; where steam or heated gases are introduced at G, and exhausted attG.

D is a dropsdoor. Y

In Iig. 2

B is a basket,made of perforated pipes;

a is a main pipe, connecting with all the perforated pipes of the basket.

c' is the bottoni of the basket, made of iron rods or perforated pipes, and attached to the basket by hinges at b3. .Eis a rod, by means of which the bottom of the basket may be dropped or raised.

pipes, showing In order to enable others to Work and apply ourinvention, we will proceed to describe the operation.

The kiln being opened, by removing thel cover or top, thus exposing `the basket or baskets, the fish or other substances, animal or vegetable,y to be dried by air o r other heated gases, are placed .in the basket or baskets BIB B, &c., and the cover or topreplaced.

Steam or heated gases are turned on' at G into ,the jacket ofthe kiln, and let exhaust at G'.

The air-pipe A, or c, is .connected with a pump or blower, and either hot air or gases from the combustion ot' fuel in aV furnace are introduced. The heated, gases or air come out i'om the Aholes of the perforated pipes, which the basket or Abaskets are made of or lfrom the perforated false top of the cover of the kiln,

take up the moisture of the fish, or whatever other substances may be placed in the basket or baskets, andl carry it-off at a.

When the fish or other matter is sufficiently dry, the cover of the kiln is taken olf, the bottom ofthe basket or baskets dropped by means ofthe rod E, and the fish or other matter is let down at the bottom of ,the kiln, and taken out at the door D.

What we claim as our invention, and desire to secure by Letters Patentof the United States, is-

1. A kiln, by which the fish or other substances, animal or vegetable, are kept separated, by perforated pipes, wire, or their equivalents, in order that the air or other heated gases may readily come in contactl with the substancesabove mentioned, for thepurpose -set forth.

2. The basket or baskets 'herein described, with movable bottom, substantially for the purpose set forth.

3. The top or Icover ofthe kiln, with a perforated false top or perforated pipes, as herein described.

4. The door D of the kiln, for the purpose as herein described.

5. The kiln with a steam or heated gases jacket for this purpose of 'controlling the heated air or gases in the kiln itself.
